A mining engineer may refer to a particular type of engineer, who specializes in the formulation of plans that deal with the engineering aspects of extracting mineral resources from the surfaces of the earth. Mining engineers may be involved in conducting investigations related to the profitable extraction of mineral deposits, for which they work in collaboration with geologists, earth scientists and economists. They research and develop scientific techniques that enable the most suitable and convenient ways to mine minerals, while taking into consideration factors like depth, deposit level and other important factors. Mine engineering is one of the most multifaceted disciplines that cover a broad spectrum of subfields including mine designing and evaluation, management of mining operations, geotechnical engineering, mining supply management engineering and evaluation of the market value of mining products. A mining engineer may have a wide variety of roles to play like technical, which may involve planning and designing mining methods, production roles and also business development roles. That may involve efficient project management and marketing. Here are some of the most famous mining engineers from across the world, learn more fascinating facts and details with their biographies that include trivia, interesting facts, timeline and life history.
